摘    要:提出了一种针对网络时延和被控对象时延的新型Smith预估器,以便有效地抑制网络时延对网络控制系统性能的影响.该预估器不包含网络时延预估模型,无需对网络时延进行在线测量、估计或辨识,适用于网络时延为随机、时变和不确定的网络控制系统.仿真结果表明,在网络时延大于1个乃至数十个采样周期的情况下,基于该新型Smith预估器的网络控制系统具有较强的鲁棒性,且具有良好的动态性和抗干扰能力.

关 键 词:网络控制系统  网络时延  Smith预估器  数据丢包  稳定性

Abstract:In order to effectively restrain the influence of network delays on the performance of networked control systems(NCS),a new Smith predictor with regard to the delays of network and controlled plant was proposed.This new Smith predictor does not include prediction models of network delays,and network delays do not need to be measured,estimated or identified on line.As a result,it is suitable for the networked control systems with random,time-variant and uncertain network delays.The simulation results show th...
Keywords:networked control system  network delay  Smith predictor  data packet dropout  stability
